3pt log splitter on Yanmar 2610's hyd ?

[KennethBrown]

My dad has a 2610 yanny and wants to hook up a 3pt log splitter. This sp;itter runs off of the tractors hyd. I don't think it'll be enough to do what he wants? I know there are a ton of variables ( how much psi and volume does trac have vs what does the splitter need) but unfortunetly I have no clue to the answer. Was wondering if anyone has done this before and how well did it work.

I'm sorry I can't give you specific answers, but I can give you generalized ideas. Hydraulic pressure is the primary contributor to the strength the splitter will have. Hydraulic volume is the primary contributor to the speed the splitter will have.

I don't think the tractor will be the limiting factor to the strength or power of the splitter, the splitter design will probably limit that. But the hydraulic volume the tractor produces will definitely contribute to the speed of the splitter.

For example, if the tractor produces 3 gallons per minute (gpm) of flow and the splitter cylinder requires 3 gallons of fluid to fully extend the cylinder, it will take one minute to complete that extension. Easy math utilized here, not necessarily factual numbers. But you get the idea.

So the splitter will probably complete the tasks required but may not have the desired speed. The simplest, but expensive, way to fix that problem would be to buy a PTO pump and storage tank and run the splitter that way. I'm building a PTO driven splitter that will have 21 gpm flow. My Kubota has less than 10 gpm flow. I expect my splitter to complete a cylinder extension in 5 seconds or less. That's my desired goal so I needed more flow than the tractor could offer. Plus my friends and family have tractors without rear hydraulics so the splitter will work on their tractors as well.

Hopefully Madreferee will see this and chime in. He's a hydraulic expert and can correct my errors plus give you technical info. Good Luck!!!

OK so lets take it a step further if you don't mind. The tractor does not have rear hyd. Is there anything wrong with disconnecting a set of lines from the loader and adding extensions? This seems like the least expensive way to accomplish this. The tractor is 31 hp, 26 at pto so I don't think he'd be running many attatchments that would operate while the tractor is moving. If this will work it would be great because then I can borrow it for my 5500 Mahindra and do the same thing.

I would take Ovrszd advice and go with a PTO driven pump. Prince Hydraulics makes a 11Gpm and a 21 Gpm. About $400 at Northern Hydraulics, even less on Ebay. The problem with plug in log splitters is cross contamination of oil and contaminates. If you lend it to someone and their oil is old and then plug it in to yours you don't know what you will get. Is his oil compatable with yours? My hydraulic system takes 2 5Gal pals and a $50 filter. That's a $150 change if I do It myself. Your PTO HP is high enough to use a 21GPM pump at 60% PTO/engine speed (1200rpm) and get a good cycle time on the LS

Yes, you can do that but you risk what Shaley is talking about. You will also still have the issue of whether the splitter is fast enough. Not having saw this splitter I don't know what size cylinder it uses. For example, the bigger the cylinder size, the more fluid it takes to cycle the cylinder to full extension. The more fluid it takes, the longer it's going to take your tractor hydraulics to complete this function.

If you don't mind the risk of contamination, then I'd try using the loader hydraulics first because that's definitely the cheapest way to get started. I've got an old homemade splitter that uses a small gas engine and a slow pump. Working alone it's not too bad. But if you have two people working, you spend more time waiting on the cylinder to retract than you do working. I hate that.

So I'm all about speed this time. But that speed has a price. I'm going to end up with $1200 in my splitter. It uses a 21 gpm pump, 19 gallon tank, filter, suction screen, splitter valve, 4.5x24 cylinder with a 2" ram. I expect it to last my lifetime and be quick.

I agree with Ovr... Tractor pressure is probably adequate.. gpm may be limiting.

I've seen plenty of log splitters run off an old ford N 2.85 gpm belly pump that made 1500-1700 psi. It worked.. but you couldn't make a living off it.. it was more for 'homeowner' use.. when you got a frined over to set in some chairs and drink frosty beverages and split wood while talking about old times and telling lies... in that case.. slow is fine...
